I won ~60 BTC there, but it was some time ago, around when they first opened.  If I remember right, they paid out 20 BTC, then quoted their T&C stating that they could only pay out 20 BTC per week and I played and lost the other 40.  A 40 BTC win on Endorphina's Safari was advertised on their site still last time I checked.  I was not asked to go through KYC at this time, I was using either a proxy or vpn, and I was never asked to fill out any personal information though I would have used false information if asked.

I don't think the Softswiss casinos were enforcing KYC as much at that point.  It seems like maybe mid-late 2015 is when both Softswiss and the casinos that were on the bitcasino.io platform is when the KYC stuff started being enforced often.  I have no first hand knowledge of this myself, but I've heard some people on this forum might be able to provide the commonly requested information for a KYC check, such as a scanned ID, utility bill, and a selfie holding said information.  They might even be willing to provide custom documents with whatever name you choose for a reasonable fee.  I've heard that Softswiss casinos will often allow cashouts if the documents are good, but bitcasino.io/vegascasino.io often won't.  I can say that Softswiss casinos all follow nearly the same rules, and if you win less than 1 BTC you'll probably be okay withdrawing without KYC.  I'm pretty sure they always require KYC if you accept a bonus and profit.

Overall, I'd recommend FortuneJack at this point.  They have most of the same game providers as Softswiss (to include Softswiss games) but rarely pull the KYC bullshit.
